Since the 44 headtube evolution has finally solidly landed on firm ground, I decided to make some time today to create new head tube pieces for the frame fixture.

For y'all that are a bit in the rears...the 44 ID headtube allows for a diverse selection of potential steerer sizes to be utilized within the space of a single frame. From straight 1.125 in a zero stack setting, to tapered 1.125 to 1.5 steerers with just an exchange of lower cups. It'll do more, but thats the meat on the plate.

I modified the old fixture for the first few frames that used this new headtube, but it was time to get the main fixture up and running. The new pieces are designed to be compatible with the bottom release puck and the micro adjust upper cone..all purge capable.

Here's a shot of the lower puck..the insert extends far enough internally to support the head tube and act as a heat sink for the downtube joint. It is drilled, tapped, and relieved on the bottom to accept the drop away bolt on the bottom of the fixture to allow the frame to slide out freely after welding.

The upper cone has purge reliefs drilled into it and utilizes a small milled slot that orients it in the fixture and limits it's micro adjust vertical height.

All together in the fixture with Keith's 44 head tube in place.

Shot through some office work and placed lot's of orders for material and parts. Off to the FD for a three day tour, see y'all soon.

For those of you who don't follow the Groovy Facebook page, the Ti road frame is completed in fabrication and we're gonna finish it in a mixture of paint, ceramic and blasted graphics to show the spectrum of finish possibilities with Ti.

Also, Kalten and I did a massive 24 hour road trip and picked up another restoration project for the future...1958 Zundapp Bella scooter.

Thanks to Dick up in Michigan for finding her and getting her functional. We're going to ride her for a few years then do a complete resto job, should be a hoot.

Hard to believe that a simple cold can turn into so much more. Bacterial pneumonia, that morphed into strep throat, that morphed into sinus infection and ear aches...is finally over. I got back to the fire department last week and worked 120 hours in seven days, then felt shitty again. Today is the first day that I feel really good, I think 3 solids nights of solid sleep really helped.

In the interim, I've been piddling through the shop work, trying to keep at it a few hours at a time. Not a lot to share that is earth shattering, but can update y'all a bit.

I was able to get the balance of the March bars sprayed up in ceramic and out, thanks everyone for their patience...

I had posted pics of Dirks race bike in the paint booth, but I also got it assembled and delivered in time for his first race of the season, which he took 6th overall in the Open Expert category...way to go Dirk!

Kalten forged a friendship with the nice folks from Rickshaw Bags while at Nahbs. As he commutes 10 miles each way to school daily they kindly selected him to beta test one of their new designs for 30 days to help them dial in any changes that are needed in the "real world". Thanks to Christy and the team for making such sweet products. I'll have Kalten post up a review here at the end of the testing period...

I've had a pile of tubes set aside to build me a road bike for about 3 years now, so I started piecing it together the last two days to get me back into the shop groove. A Ti road bike with a beefy bi ovalized down tube, .875 stays and a little higher front end than my last bike built 18 years ago as I'm not as flexy as I once was. I single pass welded the frame in the fixture and put it on the alignment table...dead on tight. No cold setting, no witch wanding, no magic fairy dust needed. Proper weld sequence, good penetration and heat control, and the right fixturing make all the difference.

If y'all follow me on Facebook, you'll know that the Groovy Jerseys arrived and look dandy. It would be nice to see them bopping around the local trails and by ways...but alas, most went to my adoring customers afar. Thanks for flying the colors y'all. Here's Carey in all his enthusiastic glory...

Glad to be back in the saddle, gonna work hard to catch up on communication, shop work, and taking better care of myself (soon).

Super Hot linkys!

About Me

Hey folks, thanks for stopping by. So...what to tell you about Groovy Cycleworks?
Groovy Cycleworks was born back in the heyday of mountain biking, the early 90's, when bright colors, lycra, and cnc parts ruled the roost.
Learning from one of the true engineering masters of cycling, I acquired a love for clean lines, strong designs, and functional elegance.
I've been doing the "custom" thing since 1994; road, mountain, tandem and a full spectrum of forks, stems, etc...
Drop me a line and we'll see if we can build the bike of your dreams.
cheers,
rody
